Abstract

The SPEX GISMO VUV spectrometer installed on JET has been used to study the impurities radiation during X-point operation. Preliminary results have been obtained with 2 of the 3 spectrometers. They concern mainly the light impurities emission, C III, O VI in the vicinity of the X-point during the transition from L to H mode. The results are reported for both single X and double X discharges and future prospects are assessed.
